摘要
采用不同的工艺参数,对3Cr2W8V模具材料进行表面激光仿生强化改性试验,并进行了显微组织,耐磨损性能、抗高温氧化性能和耐腐蚀性能的测试与对比分析。结果表明,随焊接电流从100 A增大至160 A,扫描速度从30mm/min增大至60 mm/min,耐磨损性能、抗高温氧化性能和耐腐蚀性能均先提高后下降。焊接电流和扫描速度分别优先为140 A、50 mm/min。
The die material 3Cr2W8V samples were modified by surface laser bionic hardening with different process parameters, and the microstructure, wear resistance, high temperature oxidation resistance, and corrosion resistance of the die samples were tested and analyzed. The results show that with the increase of welding current from 100 A to 160 A and the increase of scanning speed from 30 mm/min to 60 mm/min, all of the wear resistance, high temperature oxidation resistance, and corrosion resistance increases firstly and then decreases. The optimized welding current and scanning speed are 140 A and 50 mm/min, respectively.
